Probing the low-mass end of the companion mass function for O-type stars
M. Reggiani, A. Rainot, H. Sana +6
Almost all massive stars are part of a binary system. Given the wide range of separations at which these companions are found, several observational techniques have been adopted to…
The Carina High-contrast Imaging Project for massive Stars (CHIPS): II. O stars in Trumpler~14
Alan Rainot, Maddalena Reggiani, Hugues Sana +2
Most massive stars belong to multiple systems, yet the formation process leading to such high multiplicity remains insufficiently understood. To help constrain the different format…
Unveiling wide-orbit companions to K-type stars in Sco-Cen with Gaia EDR3
Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +12
Abbreviated. We aim to identify new low-mass companions to young stars using the astrometric measurements provided by the Gaia space mission and complementary VLT/SPHERE data. We i…
The 13O-rich atmosphere of a young accreting super-Jupiter
Yapeng Zhang, Ignas Snellen, Alexander J. Bohn +8
Isotope abundance ratios play an important role in astronomy and planetary sciences, providing insights in the origin and evolution of the Solar System, interstellar chemistry, and…
Multiplicity of Galactic Luminous Blue Variable stars
L. Mahy, C. Lanthermann, D. Hutsemékers +7
Context. Luminous Blue Variables (LBVs) are thought to be in a transitory phase between O stars on the main-sequence and the Wolf-Rayet stage. Recent studies suggest that they migh…
Discovery of a directly imaged planet to the young solar analog YSES 2
Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +8
Abbreviated. By selecting stars with similar ages and masses, the Young Suns Exoplanet Survey (YSES) aims to detect and characterize planetary-mass companions to solar-type host st…
A dusty filament and turbulent CO spirals in HD135344B-SAO206462
Simon Casassus, Valentin Christiaens, Miguel Carcamo +16
Planet-disc interactions build up local pressure maxima that may halt the radial drift of protoplanetary dust, and pile it up in rings and crescents. ALMA observations of the HD135…
A faint companion around CrA-9: protoplanet or obscured binary?
V. Christiaens, M. -G. Ubeira-Gabellini, H. Cánovas +16
Understanding how giant planets form requires observational input from directly imaged protoplanets. We used VLT/NACO and VLT/SPHERE to search for companions in the transition disc…
